Multiple providers, including Azure OpenAI, Gemini, and AI hosting platforms
are accessible using the OpenAI REST API and corresponding client libraries,
but may proxy or host models from different providers.

The `gen_ai.request.model`, `gen_ai.response.model`, and `server.address`
attributes may help identify the actual system in use.

The `gen_ai.provider.name` attribute acts as a discriminator that
identifies the GenAI telemetry format flavor specific to that provider
within GenAI semantic conventions.
It SHOULD be set consistently with provider-specific attributes and signals.
For example, GenAI spans, metrics, and events related to AWS Bedrock
should have the `gen_ai.provider.name` set to `aws.bedrock` and include
applicable `aws.bedrock.*` attributes and are not expected to include
`openai.*` attributes.
